How this calculator works
All figures are in today's money. We grow your pot at the rate you choose above inflation, so £30,000 in the result buys what £30,000 buys today.
- Your current pot grows each month, and your monthly payments are added, until the age you retire.
- Your yearly income from the pot is that pot multiplied by the withdrawal rate you pick.
- We add your State Pension once you reach State Pension age, and any final salary pension income.
- We compare the total, before tax, with the income a single person needs before tax to reach each Retirement Living Standard: £14,232 (minimum), £37,732 (moderate) and £54,720 (comfortable), using 2026/27 tax rates for England, Wales and Northern Ireland.
It ignores the 25% tax-free lump sum, which would make the money go a little further, and assumes you own your home outright. Our guide on how much you need to retire explains the targets.
